CC   -!- FUNCTION: Antibacterial peptide, that adopts an alpha helical
CC       conformation which can disrupt bacterial membranes. Each caerin
CC       displays a different antimicrobial specificity.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- TISSUE SPECIFICITY: Expressed by the skin parotoid and/or rostral
CC       glands.
CC   -!- MASS SPECTROMETRY: Mass=2397; Method=FAB; Evidence={ECO:0000269|Ref.1};
CC   -!- SIMILARITY: Belongs to the frog skin active peptide (FSAP) family.
CC       Caerin subfamily. {ECO:0000305}.
